Originally, Assembly Language was designed and developed with a one-to-one correspondence between machine language instructions and mnemonics. All the programs written in assembly language are dedicatedly compiled by an assembler that comes built-in with computer systems. Although, there are variety of high-level languages with their own set of advantages & downsides used for the development of applications & software, but assembly language has its own uniqueness. It has the ability of making hardware manipulation, and performance manipulation possible. It provides access to special instructions for processors.
Keep reading to know the importance of learning Assembly Language & its advantages and disadvantages as a whole!
Advantages: Assembly Language Programming
Here is the list of benefits that you can gain while learning Assembly Language:
1. Time Efficient
For starters, Assembly Language is the lowest level of coding. Hence, Compiler takes almost no time to decode it.
2. Less Memory Consumption
As we already discussed, for Assembly Language, you need to use the registers for operations. Since they are used for temporary storage purposes, you don’t need to bother about the consumption of memory.
3. Understanding Machine Language
At this point, I am already assuming that you know your system only understands two things – 0 or 1. Multiple combinations of both the numbers indicate the computer’s processor: what needs to be done and when to be done? Since, Machine Language is the computer understandable language. So, to better understand Machine Language you need to have a command over Assembly Language.
4. Interrupt Service Routine (ISR)
Well, ISR is a dedicated routine invoked by an Interrupt. Be it Software Interrupt, Hardware Interrupt or Timer Interrupt. If you have the knowledge of Assembly Language, you can easily alter and change the ISR according to your needs or preferences.
5. Low-Level Embedded System
As we have already learnt, Assembly Language is majorly used to program embedded systems such as ovens. Using it, one can easily take advantage of time and storage efficiency along with the ability to manipulate the hardware.
6. Hardware Manipulation & Processor Instructions
If you have learnt Assembly Language well, you can easily manipulate hardware accordingly.
Disadvantages: Assembly Language Programming
Advantages & disadvantages goes parallelly. Now that we have seen major benefits of learning Assembly Language, here are some drawbacks with it:
1. Not Designed For Small-Sized Computers
Well, long programs written in Assembly language are difficult to execute and the results are mostly negative. Therefore, you cannot code in Assembly Language on Small-Sized or dated systems
2. Varies By Microprocessor Type
Assembly Language programming may differ from Microprocessor to another microprocessor. The written program is not independent of the portable platform.
3. Difficult To Understand
Unlike other programming languages, to write in Assembly language, one must know the internal structure of the microprocessor to proceed further.
Why Should We Learn Assembly Language?
Learning the Assembly Language is quintessential for programmers. Once they learn the language, they will be able to write codes to access registers and easily retrieve memory addresses of printers and values by learning Assembly Language thoroughly. Despite the prevalence of high-level languages, which are mainly used for developing applications & software, the importance of Assembly Language in today’s world is highly underestimated. Undoubtedly, a programmer can gain a lot if he/she learns to code in Assembly Language and implement as and when required. The main uses of Assembly Language Programming include: Coding device drivers, real-time systems, reverse engineering and more.
One of the major benefits of learning Assembly Language is it helps in manipulating the hardware directly, manage critical issues when it comes to hampered performance and proffers access to special instructions for processors.
Conclusion: Assembly Language Programming
Many computer programming languages are used for the development of applications and software programs, the importance of assembly language cannot be underestimated. With Assembly Language, you’ll be able to run complex tasks in simpler ways, doesn’t track much of memory locations and it is relatively faster in speed as execution time is quite less. Additionally, the assembly language programming is transparent in nature as compared to other high-level languages. This is because it has a small number of operations. Therefore, it finds many users in algorithm analysis. It makes it easy to debug. Moreover, it is the language that the CPU easily recognizes. Since every section of binary caters to a certain meaning, it can be somewhat easy to understand, in comparison to other high-level languages!
